Jax is mostly identical to his Mortal Kombat 3 version. He doesn’t gain any new move or animation, but the general ability to start combo after a jump punch or kick.
Jax has many special moves. He has his Bionic Rush technique, which causes him to fly toward his opponent to punch him. He can also shoot either a single fire ball or two in succession, pushing him after the first. He keeps his Ground Smash move that is good to use as a combo under. He also keeps his Gotcha Grab, complete with the HP tapping to punch to a maximum of five times in a row. Lastly, he has two unique throws. His backbreaker air throw is back and is an excellent way to catch an opponent as he is about to land. His regular throw can also be done four times in succession if HP is tapped quickly.
Jax’s main strategic is to lure his opponent toward him in order to perform his very damaging combo. In order to do this, shooting projectile will prove effective. His multi-throw is also quite damaging, going as high as 24%. His Bionic Rush is only useful at the beginning until the CPU crouch from hit and uppercut him. However, against the boss, it can be spammed. His Gotcha Grab, while rarely coming into play, works against the four bosses and will knock them down after the final hit.
